.To all whom it mayA CUI/wein.'

Be it known that I, OHARLEsConAHAN, a citizen of the United States-offAmerica, and a resident of Chicago, in the-county .of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

My invention has reference to mechanism accessory to the tying of the knot in binders of the Appleby type, and more particularly to that form wherein the cord-slot has an oblique angular jog over the Ain ner inclined edge of which the cord is laid 'and by which it is guided close up to the spindle of the knotter, the latter normally standing with its bill trending outward inthe general direction of the outer or return reach of said-.jog and past the inclined edge of the-inner reach and stopping in such position after each knotforming revolution.. In this construction it sometimes happens that the jarring of the machine or the pressure of straw will causeY one or both strands of lthe cord that are laid over the knotter, particularly the strand at the outer side ofthe bundle, to slip around the jogr inpthe cord-slot, or, in other Words, around the salient finger forming one side of this jog, and displace the two ends leading to the cord-holder, so that they will notbe seized by the knotter-jaws as the latter close, and thus the knot fails -to be formed. To remedy this, I have heretofore proposed, in Letters Patent No. 690,134, granted to me December 31, 1901, to locate a projecting boss or knob in the slot immediately outside of the aforesaid salient linger tofintercept the strand or strands escaping therefrom and guide them by the inner bevel of the knob back into position tobe seized by the knotterjaws. This, however, in some measure obstructs the slotrwhen the completed knot is to be pulled from the knotter by the action of the ejection-arms. Therefore in the present invention I propose to substitute for this stationary boss a movable boss, which is normally projected slightly within the cord-slot immediately beneath the knotter near the rentrant angle of the slot in the, breastplate, the inner curved walls of the projected boss being slightly in advance of the outer side of thevertical knotLer-shaftlo provide a suitable deliector adapted to restore or maintain the strands of cord that pass'around the bundle in position at the side of the knotterjaws as the 'strands vextending to the cordholder are Wrappedaround them in the revolution of the knotter and seized upon by said knotter-jaws as they come around in grasping position,-thus securing a perfect loop, when the movable boss is positively withdrawn bythe action Ofthecam-Wheel and the loop pulled over the ends held'within the tying-bill as the .cord strands extending down around the bundle beneath the breastplate move alongthe oblique angular face of the breastplate, stripping the cord Yfrom the tying-bill by the force of the outgoing bundle as it is ejected from thebinder.

In the drawings, Figure l is a view, partly inverticalV section, showing the horizontal movabley boss connected to its vertical actuat- Aing-shaftthat receives its motion from a camsurface on the periphery of the knotter-actuating Wheel. Fig. 2 is a plan view in section VOnline 2 2 of Fig. l, showing the slot in the breastplate, the cord holder and knotter having nearly completed their movement, and the movable arm with a projecting detlecting boss extending Within thev open slot to prevent the escape of the cord and direct'it to the knotter-jaws. Fig. 3 is a plan view of samepas the knotter has completed its revolution and the cord is being severed by the knife. Fig. 4 is a sectional view of the'breastplate and the vibrating-arm with its deiiecting boss in its normal position, while the dotted lines show. the arm and its boss or deiiector withdrawn to permitthe discharge of the knot. Fig. is'an edge view of thecam on'the periphery of the knotter-wheel als-it actuates the vertical shaft ofrthe vibrating arm to cause its withdrawal at the moment the knot is being stripped, the-straight track on the periphery of the wheel each side of this cam serving to maintain the arm and its projecting boss in its normal position across the extended reach of the cord-slot.

I have found it most convenient to make the movable arm as a horizontally-vibrating arm and the deector on the end of said arm as an inwardly-beveled knob, such as shown in my aforesaid former patent.

In the drawings, A represents the breast- I plate; B, the knetter-spindle; B, the knetter or tying-bill, which stops with itsjaws trending outwardlyin the direction of the discharge of the bundle; C, the cord-holder shaft.

C is the cord-holder shoe; C2, the cord-cutting knife. 4

F is the main knetter-driving gear-wheel; D, the cord; E, the supporting and actuating shaft of the horizontally-vibrating arm; E', its projecting boss and rounded stop that in its normal position extends within the open slot. Ate is represented detlector or convex raised portion ofsaid arm. E2 represents the crank of said arm, having the actuating-pins e2 e2, that contact with the flange F', which is provided with the cam f.

G represents the oblique reach of the cordslot.

In operation the band being placed around the bundle and across the knetter-jaws in the usual well-known manner, the knetter will revolve over the breastplate that holds the cord well up on the jaws near the knettershatft, and as the end extending to the cordhelder is seized beneath the vibratingjaw the cord extending down around the bundle and supported on the oblique reach or face of the cord-slot or salient finger G of the breastplate is intercepted in case of slipping over the outer corner by the projecting boss or knob and deflected back to tying position until the cord is eut and the ends seized and firmly held beneath the vibrating jaw, when the boss or deliector is withdrawn by its vibrating arm, and then the outward discharge of the bundle will strip the knot from the tying-bill, as shown in my former patent, No. 690,134, December 3l, 1901. p

Having thus described my invention, what I claim, and desire te secure by Letters Patent, is-

1. In combination, the breastplate having an angular jog in its slet, an obliqnely-extended finger at the salient angle formed by the jog over the inner oblique edge of which the cord is laid, the knetter revolving over said breastplate in proximity to said finger, and stopping withitsjaws trendingoutwardly in the direction of the discharge of the bundle, the movable arm beneath the knetter adjacent the rentrant angle of the slot and having on its upper surface a raised portion and its end normally projecting into the slot to deflect escaping strands into position te be grasped bythe knetter-jaws, and the knetterdriving wheel having means for normally holding said arm beneath the knetter prejected within the cord-slot and positively withdrawing it the instant the cord ends are grasped in thc knetter-jaws.

2. In combination with the breastplate having an angular jog in its cord-slot, an ebliquely-extended salient angle formed by the jog over the edge of which the cords are laid and by which they are deflected toward the knetter-spindle, the knetter revolving over the breastplate in proximity to said angle and stopping with its jaws trending outwardly in the direction of the discharge of the bundle, the movable arm immediately beneath the knetter, beyond the rentrant angle o the slot, and having a cord-dellecting boss upon the upper surface of that portion toward the cord-slot, and positive mechanism for normally holding said arm projected within said slot and temporarily withdrawing it the instant the cord ends are grasped in the knetter-jaws.

3. In combination with the knetter revolving over the breastplate and stopping with its point trending outwardly in the direction of the bundle-discharge, the breastplate provided with an angular slot, on the transverse face of which the cord rests in the formation. and discharge of the knot, and a horizontallyvibrating arm pivoted in the knetter-frame grainward of the knetter-shaft, and actuated byits cam-wheel, said arm being provided at the upper surface of the portion adjacent the slot beneath the knetter with a raised curved portieri and said arm terminating in a knob or boss, that in its normal'position extends below the knetter over the oblique slot to hold the cord up to the knetter, and prevent its escape during the formation of the knot, and the knetter-drive wheel provided with means for imparting the movement to the vibrating arm to cause it to withdraw therefrom as the bundle is discharged to permit the band to move over the outer curved face of the oblique slot, to tighten the knot as it is stripped from the tying-bill.

4t. In combination with the knetter revolving over the breastplate and stopping with its point trending outwardly in the direction of the outgoing bundle, the breastplate provided with an angular slot and having a horizontal vibrating arm, said arm being provided at the upper surface of the portion adjacent to the slot beneath the knetter with the raised curved portion and terminating in a knob or boss, that is caused to advance within the reentrant angle ofthe cord-slot at its outer corner and prevent the escape of the'cord that is supported against the oblique angular face of the breastplate in the formation of the knot, and the knetter-drive wheel provided with means for imparting the movement to the vibrating arm to cause it to withdraw and permit the escape of the band over the outer angular face of the preastplate as the bundle is discharged.
